And.......? Really.....the "emotional argument"?
Your argument is not stated anywhere in the passage presented that proves Sin (the breaking of God's Law) is an individual responsibility........no one is born into sin, except........death, created by Adam's sin. Oh.......woe is me, how could anyone worship and serve a God that would kill children?
Your feigned outrage does not replace the righteousness of God. (James 1:20)
Are you speaking of the children that God had put to death to end the human sacrifices to those who worshiped Baal and other false gods, some who had the children stolen from the Hebrews and put to death at a burning alter? (1 Sam. 15:1-9) Or.......the death of Egyptian first born placed to death?
This complies exactly with everyone not being born into sin..........Children are born innocent, BORN innocent until they reach the age of reason with the mental reasoning to know they are breaking the Laws of God. There is a particular knowledge that everyone gains with age, its called Wisdom, its then we first become accountable to the Laws of God. (2 Tim. 3:15). It is the innate duty of all parents to teach our children to fear God and obey His Laws, when the parents........in this case Idol Worshipers that worshiped false gods through sacrificing Humans at a false alter, they suffered God's righteous judgment.
God did not destroy the offspring because the children were being punished because THEY HAD SINNED..........but, God vowed to destroy these Idol worshipers entire lineage from the face of the earth.
The simple truth. It was better for these children to die before they reached the age of reason as taught by their parents. Innocent Children do not face judgement, they enter the Father's House automatically at death.
Which is better........allow these children to live and grow under the teachings of their clan (Idol Worship and Human sacrifice) or to die while innocent void of any accounting of the LAW? Its the human soul that God saves......not the flesh. Its the entire message presented in the Word of God. All men die......Jesus provides a path to save the human soul.......He's is not interested in feeding the flesh, but the Spirit of Man (John 6:26-27)
